Description

Technical Field

[0001] The utility model relates to the technical field of automated transportation, in particular to a power locomotive and a rail transportation train for automatic sorting. Background Art

[0002] With the development of automated logistics systems and automated warehouses, RGV (automatic guided vehicle) trolleys have emerged. RGV trolleys can be used in warehouses with various high-density storage methods. The trolley channel can be designed to be arbitrarily long, which can increase the storage capacity of the entire warehouse. There is no need for forklifts to enter the aisles during operation, making it safer. By taking advantage of the fact that forklifts do not need to enter the aisles, combined with the rapid operation of the trolley in the aisles, the operating efficiency of the warehouse can be effectively improved.

[0003] In the prior art, conventional RGV systems are usually composed of a power system, a guidance system, a control system, and a transportation system. These systems are usually integrated into a single vehicle, so that each RGV independently completes all functions of power drive, guidance control, and cargo transportation. The problems caused by this include at least:

[0004] 1) Since each RGV is equipped with an independent drive system, each vehicle needs to carry a corresponding battery or power device, which not only increases the weight of the vehicle, but also causes uneven power distribution of a single RGV, reducing the efficiency of the system;

[0005] 2) Since each RGV requires a complete control system and guidance system, the structure of each vehicle is complex, and the manufacturing and maintenance costs are high;

[0006] 3) In some application scenarios, it is not necessary for each vehicle to have independent power and control capabilities. For example, in scenarios where only simple transportation tasks are required, independent power and control systems will result in waste of resources and increased costs. Utility Model Content
